You are driving north through an intersection in a 55 mi/hr speed zone, when the local chief of police, who is driving his new cadillac and approaching the intersection from the west, hits you broadside. the two cars stick together and skid a distance 23.8 m with locked wheels at an angle of 63.3° to the east of north. the mass of your car is 1568.0 kg while the cadillac has a mass 1940.0 kg. the coefficent of sliding friction is 0.90. the chief of police is angry that you have damaged his new cadillac and gives you a ticket for speeding. the local judge is going to believe his chief of police rather than some out-of-town student. you realize that the knowledge you learned in your physics course is your only hope for acquittal. compute the speed of the chief of police immediately prior to the collision.

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.
